Two conductors carrying equal and opposite changes create a non-uniform field as shown in fig. What is the capacity of this capacity if the field along Y-axis varies as E=(Q)/(epsilon_(0)A)[1+"By"^2]with B = constant

Answer»

`C=(epsilon_0A)/d`
`C=(epsilon_0A)/(d[1+(1)/3Bd^2])`
`C=(epsilon_(0)AB)/(2D)`
`C=(epsilon_0A)/(d[1+(1)/2Bd^2])`
